Thanks for your question.
It is unlikely you still have bacterial infection as this would have been seen in blood or urine tests.
Also white blood cell count will be elevated as response to infection.
Your symptoms can be caused by the viral infection.
Viral infection improves by itself with strong immunity.
Antibiotics do not help.
Besides, probiotics, you should also take lot of vitamin C at least 1000 mg daily, zinc 30 mg daily to boost your immune system.
Fresh fruits and vegetables are good to boost your immune system.
